请教，遇到这个问题：
./kk init os -f config-sample.yaml -s ./dependencies/

Error: unknown command “init” for “kk”
Run ‘kk –help’ for usage.
unknown command “init” for “kk”

    dongweibh ./kk -help 就知道了，kk没有init参数啊，是不是搞错了，应该是create吧

      请教各位老师，在安装文件中增加了nfs-client,安装失败，去掉nfs-client就正常。

        hongming
        是按照例子配置的有一个centos7.6的集群，安装没有问题，redhat7.6的集群在nfs-client的位置一直报错，
        这是centos7.6的配置文件：

        这是redhat7.6的配置文件：

        最后在redhat的上面是分三步安装成功的，第一把ClusterConfiguration的安装配置注释掉，只保留Cluster部分，然后手工执行helm install 按照 nfs-client ,再把ClusterConfiguration的内容恢复，再执行 ./kk create cluster -f XXXX.
        是这样成功的

          13 天 后

          安装成功，查看pods状态，发现calico的node一直在重启，卡了好几天了

Your Kubernetes control-plane has initialized successfully!

To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  https://kubernetes.io/docs/concepts/cluster-administration/addons/

You can now join any number of control-plane nodes by copying certificate authorities
and service account keys on each node and then running the following as root:

  kubeadm join lb.kubesphere.local:6443 --token rajfez.t9320hox3sddbowz \
    --discovery-token-ca-cert-hash sha256:99f5f95e912acb458719c9cbaa6d4acb5d36ca0e38dccb00c56d69c2f0ef7fa2 \
    --control-plane 

Then you can join any number of worker nodes by running the following on each as root:

kubeadm join lb.kubesphere.local:6443 --token rajfez.t9320hox3sddbowz \
    --discovery-token-ca-cert-hash sha256:99f5f95e912acb458719c9cbaa6d4acb5d36ca0e38dccb00c56d69c2f0ef7fa2

                使用kk离线安装的话,k8s版本能自己选择版本吗，而不是使用默认的1.17.9版本?

                  我看了下离线包里面k8s相关镜像版本是1.17.9的，应该离线安装包只能安装1.17.9版本

                  2 个月 后

                  请教老师，第一次安装失败，第二次安装时修改了kubeservicecidr和kubepodscidr，kube-apiserver启动失败；

                    k8s不支持直接修改podcidr和servicecidr， 需要修改的话建议删除集群重新部署，当然也有保留集群修改cidr的方法，但是很复杂。

                    修改配置文件中cidr后，把kubekey/network-plgin.yaml也删除下，然后再重新部署。
